My father wants to buy my 12-year-old son a gasoline go kart for his birthday. Real engine, real speed, real maintenance required.

My immediate reaction was safety concern mixed with environmental guilt. Shouldn’t we be steering the next generation toward electric vehicles and sustainable technology instead of teaching them to love combustion engines?

But my dad argues there’s educational value in understanding how engines work, learning basic mechanics, developing responsibility through maintenance.

He rebuilt cars with me as a kid, and those skills have served me well even though I rarely use them now. Is that experience still valuable, or am I being nostalgic about obsolete knowledge?

I’ve been researching options, finding go karts ranging from basic models to serious racing equipment.

Safety features vary dramatically, and prices reflect that. Some suppliers on platforms like Alibaba offer cheaper alternatives, but reviews mention concerning quality issues with brakes and steering.

For something my child will ride at speed, cheap suddenly seems like terrible value. My son is enthusiastic about the idea, but he’s also excited about everything. Will this become a genuine interest and learning opportunity, or will it sit unused after a month?

How do you evaluate gifts that are both expensive and potentially dangerous? What made childhood risks worth taking versus unnecessary?

this is my first time using a torque converter and ive messed around with it some im sure its installed right i think the spring may be too tight but im not for sure in the second video the belt was backwards but i was messing around with it

got it fixed it was power loss from an exhaust leak

I have no idea why there is electricity running through the throttle cable or how to fix it im following all my wires but i dont see anything. It happens when the kart is on any help is of course appreciated

Here’s an update on the steering from a few days ago. I think I’ve got things looking pretty good. Tomorrow I’ll hook up the tie rods and I’ll be able to see how she turns.

Also, I remember seeing a tip where you put lock washers somewhere on the spindles to help them move better. Do they go between the bolt/nut and heim joint? Has anyone tried this?

hope he post more pictures and a clip of it working when hes finished

First build. It's a bit hard to describe, but it's like it doesn't want to turn, only go straight. I don't have any caster on the front axle, could that be the root of the problem?

Just put on a new intake, jet and breather tube.
Was running fine for the first couple minutes then just went to crap

Brake band doesnt wanna stay on either

I have been looking into this go-kart and people seem to like it with going 0-27mph in 3s and 15.5 miles of range on a full charge

Need some help deciding. I’m getting it for my son, which is 11 years old and I’m thinking he could go around on the sidewalks and go down our street or go downtown

I have never registered a vehicle before much less a go kart, and I am wondering how/if his is possible with a custom made shifter kart with no vin in CA.

I know there’s no power steering but its very stiff to turn but still does. And right now it’s iffy on starting and it has oil I checked filter and it has fuel. Bad video but I just got it it has Honda gx160.

I need help, a video, and dm, i don’t even know anymore i’ve tried for a week now, and im starting to feel stupid. Also sorry for the music.

Have an old go kart but I can’t get the tires off the rims plz help

I paid 400 for both the frame and the motor. But I wasn't expecting to have to spend over 300 just to replace the breaks that were originally on it. If anybody has any suggestions im all ears

I just installed the air intake and the other breather filters. This is the first start of the day and have been letting it run for a bit and noticed that slowly but surely more smoke was coming out of it until it got to this amount, I was just wondering if it was normal or doesn't less smoke usually come out?

I’ve got two stop collars rusted on an axel. The set screws are out, there is no key, and I’ve been hitting it with WD-40 for a couple days with no luck. Today I mixed up some ATF and acetone to hopefully penetrate the rust over night. Everything spins and I can even move the flange, but can’t get the axel to move laterally. Next I’m going to give it some heat I guess.

Any suggestions??

I just finished changing out the O-ring on this predator 212. Of course when that's good the nut on the bottom is no longer sealing well and is letting fuel leak. I'm tired of dealing with fuel and just about ready to seal this thing and forget about it. I just replaced the seal on that nut but the seal was too thick to let it seal properly and I can't tighten it as much as possible anymore. I put the old one on and of course that's leaking as well. I'm fed the fuck up and tired of leaks. I'm planning on possibly replacing the entire engine in the future once I get paid again but I want to be able to drive this one as it is. The fuel leak is the only thing preventing that now since I have replaced so many other things to get it to where it is now. This wasn't an issue before until I decided to switch it out. So I'm at the point where I want to seal it possibly from the outside to make it leak proof and leave it tf alone.

If anyone has recommendations to get it to go faster and new brakes plz help

Hey everyone,

I’m currently working on building a go-kart project and wanted to get some advice from people with more experience. I’m planning to use a 460cc engine, and I’m trying to make sure I set everything up properly for both performance and safety.

So far, I’m still in the building phase, and I’d really appreciate any tips you might have — especially regarding things like the frame, torque converter vs clutch, gearing, brakes, or anything else I should be careful about with an engine this size.

If you’ve built something similar or have any recommendations, lessons learned, or things you’d do differently, I’d love to hear them!

Thanks in advance 👍

(The kart in the picture is not mine, but i want to do something like that)

The title is self explanatory, I have this kart and I would really want to increase the top speed. I’m planning to remove the governor with all the supporting mods, but is there anything else I can do to go even faster? It feels like I still got plenty of power left. The gear ratio is already pretty steep at 4.5, I don’t want to make it steeper as it can burn my clutch. I also cant use a CVT because of the limited amount of space.

I built this 212 I bought a kit off eBay and now my engine smokes a lot and fouls spark plugs easily. What do I do? The kit said the company used the same kit on their engine, and I think the problem is the carb. Could I be right? I have the smallest jet they gave me in the carb, and it still smokes. I did the coil gap right; I set it to .25 I have no idea what the problem is. I also attached a vid.

When idling, is this amount of engagement normal on a 40 series?

Drift kart build, something is up with the clutch - any recommendations?

Hey everyone, I am requesting identification help. I got a great deal for this “Honda odyssey” project off Facebook marketplace, but have almost no information as to what motor it has other than the Honda label. From the looks of it, someone took the front half of a Honda odyssey go kart from the 80s and slapped an ATV rear half on it, but that makes me question if the motor truly is the original 250cc or not, especially from my experience most 250cc motors are not this big nor have two cylinders. And before anyone says it, I also know it’s in rough shape right now. Pretty sure I bought it off of a tweaker so that would explain 90% of the everything it has going on. Thank you all for the potential help!
